High-fat diets make us stupid and lazy?

Ripped that headline right from the FASEB Journal. Link to study here, link to article in NYT here.

Basically, according to the study, consuming fatty foods negatively rapidly affects your short-term memory and energy levels SIGNIFICANTLY.

The conclusion of the study is that "optimization of nutrition to maximize the efficiency of mitochondrial ATP production could improve energetics in athletes and patients with metabolic abnormalities."

Current Running Mix

This is the current mix I use for running. It's 26 minutes, 48 seconds, and I never get all the way through Black Cat (only run for about 20 minutes - 2 miles... for now).

01 - Sweet Spots (The Fiery Furnaces - EP)
02 - Bodysnatchers (Radiohead - In Rainbows)
03 - Cuddle Fuddle (Passion Pit - Chunk of Change)
04 - Black Cat (Ladytron - Velocifero)

This is a good mix.

NPIV - N_Port ID Virtualization

NPIV is a technology standard for fiber channel that allows you to assign multiple initiators (OS instances) to a single HBA port. Each initiator can have its own unique WWPN.

The idea seems to be that NPIV allows you to access the HBA directly from the OS, instead of through a virtualized device provided by a hypervisor. I think it essentially offloads the port arbitration to the HBA itself. Another advantage is that the SAN can now see your OS directly (your OS's WWPN), so, again, you don't have to fumble around w/a virtual device, trying to figure out what is going where.
